Australian Federal Police (AFP) have apologised to families of Australian victims killed in a plane crash in Nepal last month, following sensitive documents related to the crash being found by guests on a hotel computer in Kathmandu.

Australian diplomatic cables and police documents were left in open files on a computer available for public use at the hotel, Fairfax said.

At least 20 police photographs of the charred remains of crash victims could be seen by guests for up to three weeks.

A guest told Fairfax he deleted documents that were on a USB memory stick left in one computer.

Three weeks later he found photographs of the crash victims on another computer in the hotel’s business centre.

In a statement released today, the Australian Federal Police confirmed a number of its officers responded to the crash which claimed 18 victims, including Australians Andrew Frick McLeod, 31, and his girlfriend Charlene Kate Zamudio, 24.

The AFP team assisted Nepalese authorities to identify the victims of the crash and enable their repatriation back to Australia, the statement said.

“The officer allegedly involved in the security breach will be returned to Australia to assist the investigation.”

“Whilst the full circumstances surrounding the security breach are yet to be established, the AFP has spoken to the families of the Australian victims and unreservedly apologised for any additional distress it may have caused.”
